In the sand and gravel aggregate production line, crusher, as the key core equipment, plays a key role in the whole production line. Especially under the fierce market competition, many enterprises and individuals have gradually entered the sand crushing production industry, and the related crushers must be comprehensively compared based on the different uses of the industry needs, to make sure the selection of crushers is effective and reasonable.
This article will tell you how to maintain 4 types of commonly used stone crushers and how to effectively improve their performance.
Jaw crusher has the characteristics of simple structure, stable operation, wide application range of materials, simple operation and low maintenance rate, but it is necessary to regularly check and replace the wearing parts such as dynamic and static jaw plate and side protection plate.
In the process of daily maintenance, it is necessary to check the eccentric shaft, the dynamic jaw plate and the lining plate of the jaw crusher, pay attention to the long-term continuation of this work. In addition, it is necessary to clean up these key components in time, and do a good job of recording, maintenance, replacement and other work.
By following these guidelines, you can maintain and improve the performance of your jaw crusher, which can help increase productivity and reduce downtime.
During the working process of cone crusher, it is necessary to ensure continuous and uniform feeding of materials to achieve full chamber crushing of the crusher to improve the production capacity and crushing efficiency, and to avoid situations such as eccentric feeding, insufficient feeding, excessive material smaller than the tight edge discharge port (generally≤10%), and high powder content in the material. At the same time, the material to be crushed should not exceed 80% of the maximum feeding size allowed by the specific model of the cone crusher.
In general, we can adopt the following methods to improve the production effect of cone crusher:
Before starting or stopping, it is necessary to establish an effective operation and maintenance mechanism based on the actual situation to ensure the normal start of the cone crusher;
Reasonably select and design the particle size, feeding amount, and distribution method of the material to avoid abnormal shutdown;
Choose proper lubricant to promote good lubrication between the lubrication parts of the cone crusher;
Establish and improve the daily inspection system;
Reasonably arrange the monthly, quarterly, and annual inspections of equipment to form a practical operation and maintenance system, and establish emergency measures.
The impact crusher is mainly suitable for coarse, medium, and fine crushing of soft and medium hard materials, and also has a certain shaping effect. The particle size of the material after impact crushing is relatively good.
Impact crusher has many advantages, such as practical, low power consumption, and lower operating cost.
However, there are also certain shortcomings, including the presence of high dust content during the crushing process. During operation, it is necessary to regularly check the wear of the impact plate and impact block, and adjust the gap between the impact frame and rotor timely according to production needs according to the required particle size and output capacity to determine the appropriate discharge port.
Hammer crushers are used to crush a variety of materials, including coal, limestone, and gypsum. To maintain a hammer crusher and ensure that it operates at its best performance, you can follow these general guidelines:
(1) Before starting the machine, it is necessary to conduct a comprehensive and detailed inspection of the control equipment before the crusher process to determine the reliability of the equipment, and also to ensure that the functions of the crusher.
(2) During the startup process, make sure that there is no debris and materials in the crushing cavity. And feed the raw material to the crusher after a few minutes of no load running. And ensure that every shift needs to check the bearing, hammer head and bolt, to avoid loosening of bolts, bearing oil shortage, hammer head excessive wear.
(3) Regularly inspect the operation of the motor and the temperature rise of the bearings to reduce the occurrence of safety accidents.
(4) After production, the operator must check whether all the materials in the hammer crusher have been completely discharged. If they are not discharged or there are impurities, they need to be completely removed.
There are many types of stone crusher machines on the market. In this article, we will introduce the types and price of the stone crusher and how to select the most suitable one.
Jaw crusher and cone crusher have similar crushing principle, but different in many ways. In this article, we mainly talk about 9 key differences to help you choose the right crusher.
Cone crusher is widely used in mine production due to its high crushing efficiency, low maintenance cost and large output capacity.
